ABERDEEN, Md. --- Tell a Soldier he's loading "environmentally friendly" ammo into his M4 mag and he might be skeptical about whether it's as effective as its lead counterpart.

But Army officials here say the new M855A1 Enhanced Performance Round -- with its steel core instead of a toxic lead slug -- is far more effective than the current round, doubling the effective range and for the first time giving M4-wielding Joes the ability to penetrate barriers once reserved for higher-caliber rounds.

"There's a stigma among Soldiers about something that's 'green,' " said Lt. Col. Jeff Woods, the Army's small caliber ammunition product manager. "This is a clear case where making something environmentally friendly works for us."

Leveraging the science of 120mm tank rounds, Army engineers at Picatinny Arsenal, N.J. designed a 5.56mm rifle cartridge that incorporates a jacketed copper slug pushing a sharpened steel "penetrator." Testers showed during a May 4 demonstration here that the round can punch through quarter-inch steel armor out to 300 yards with ease.

How to kill two birds with one stone. Green and effective... Anyway i think that, in order to " double the effective range" they have to load this M844A1 with a different kind of powder, too. Infact, they probably had to increase the bullet speed using a more progressive gun powder. It would be interesting to know something about the weight of the bullet. It's the weight of the bullet the main factor needed to determine the quantity of gun powder.

It is comforting to know that killing people with lead free projectiles will not harm the environment.

This will avoid environmental atrocities such as this lead-based outrage.
